Electronic device having lever with precision pivot
View Patent ↗An exemplary electronic device includes a housing, a lever, and a locking device securing the lever on the housing. The housing includes a bottom plate, a top plate and a side plate connecting the bottom plate with the top plate. The locking device includes a nut having a main body extending downwardly into the lever, a screw extending upwardly through the top plate into the nut, and elastically deformable gaskets sandwiched between the top plate and the nut. The lever is disposed on the top plate and sleeved on a pole of the nut. The lever is pressed by a head of the nut against the top plate.
1. An electronic device comprising:
a housing comprising a plate;
a lever disposed on the plate; and
a locking device comprising:
a nut comprising a head abutting against the lever and a main body extending downwardly from the head, the main body of the nut being received in the lever;
a screw extending upwardly through the plate and threadedly engaged in the nut; and
a bent gasket sleeved on the screw and elastically compressed between the main body of the nut and the plate;
wherein the lever is sleeved on the main body of the nut and movably held between the head of the nut and the plate; and
wherein the bent gasket is received within and surrounded by the lever.
2. The electronic device of claim 1 , further comprising another bent gasket elastically compressed between the main body of the nut and the top plate, wherein the another bent gasket is oriented symmetrically opposite to an orientation of the bent gasket.
3. The electronic device of claim 1 , further comprising at least another bent gasket elastically compressed between the main body of the nut and the top plate, wherein the total number of bent gaskets is proportional to a thickness of the lever.
4. The electronic device of claim 1 , wherein the head of the nut has an outer diameter larger than that of the main body of the nut.
5. The electronic device of claim 1 , wherein the bent gasket is made of metal.
6. The electronic device of claim 1 , wherein a sum of a height of the bent gasket before being compressed plus a height of the main body of the nut is larger than a thickness of the lever.
7. The electronic device of claim 1 , wherein the screw comprises a head and a pole extending upwardly from the head, the pole of the screw having an outer diameter smaller than that of the main body of the nut.
8. The electronic device of claim 7 , wherein the head of the screw abuts against a bottom face of the plate.
9. The electronic device of claim 7 , wherein the pole of the screw extends through the plate and is threadedly fixed in the main body of the nut.
10. The electronic device of claim 1 , wherein the electronic device is a storage bridge bay canister.
11. The electronic device of claim 1 , wherein the lever directly contacts a bottom face of the head of the nut.
12. An electronic device comprising:
a housing comprising a plate;
a lever disposed on the plate; and
a locking device comprising:
a nut comprising a head and a main body, the main body extending downwardly into an end of the lever;
a screw extending upwardly through the plate into the main body of the nut; and
an elastically deformable gasket sandwiched between the main body of the nut and the plate and being elastically compressed to hold the nut in position relative to the plate;
wherein the end of the lever is rotatably sleeved on the main body of the nut and held between the head of the nut and the plate; and
wherein the gasket is received within and surrounded by the lever.
13. The electronic device of claim 12 , wherein the gasket is a bent annulus elastically compressed between a bottom face of the main body of the nut and a top face of the plate.
14. The electronic device of claim 13 , further comprising another gasket stacked on the gasket, wherein the gasket and the another gasket are bended towards opposite directions, respectively.
15. The electronic device of claim 13 , wherein a sum of a height of the gasket before being compressed plus a height of the main body of the nut is larger than a thickness of the lever.
16. The electronic device of claim 12 , wherein the screw comprises a head and a pole extending upwardly from the head, the pole of the screw extending through the plate and being fixed within the nut, and the head of the screw abutting against a bottom face of the plate.
17. The electronic device of claim 12 , wherein the plate forms a step for blocking over-rotation of the lever.
18. The electronic device of claim 12 , wherein the gasket is spaced from and does not contact the lever.
19. The electronic device of claim 12 , wherein the electronic device is a storage bridge bay canister.
20. The electronic device of claim 12 , wherein the lever directly contacts a bottom face of the head of the nut.
